CULTIVATOR.

SPECIFICATION formihg part of Letters Patent No. 357,202, datedFebruary 8, 1887.

Application filed August 26, 1884. Serial No. 141,521. (No model.)

.To all whom it may concern:

Be it known that I, S. TERRY HUnsoN, of Riverhead, county of Suffolk, and State of New York h'ave invented a new and valuable Improvement in Cultivators; and I do hereby declare that the following is a full, clear, and exact description of the same, such as will enableothers skilled in the art to which it pertains to make and use it, reference being had to the drawings which form part of this specification.

My invention relates to riding-cultivators that have angular motion imparted to the wheels for the purpose of guiding the machine.

The objects of my improvements are, first,

to place the guidance of the machine under control of the driver by means of a swivel-gear operated by directacting foot-levers, and to support the said levers, their stirrups, and the feet of the driver from the pivot-bearings alone; second, to reduce the friction of the pivot-bearings, to protect said bearings from the destructive action of mud and dust, and to insure perfect lubrication of the parts under all conditions; third, to efl'ect an adjustment i of the entire swivel-gear with reference to the frame, so that the distance apart of the footlevers and stirrups may be changeable to suit the habit and convenience of the rider, and by the same means change the wheels to suit wide or narrow rows; fourth, to furnish an adjustable yoke-connection, by which the parallel ism of the wheels can be maintained under different adjustments of the swivel-gear upon the frame; fifth, to provide a more convenient and effective adjustment of the gangs of plows with reference to the corn-row; sixth, to simplify the construction of the controlling-lever and means for compelling the teeth to enter hard ground. I attain these results by the devices shown in the accompanying drawings, in which* Figure 1 represents a rear view of the carriage, Fig. 2 is the adj ustable pivot-bearing, and Fig. 3 shows the same casting as applied to the frame. Fig. 4 is the rightside pivotspindle, with outwardly-projecting axle and inwardly-projecting foot-lever having stirrup attached. Fig. 5 is the rock-arm fitted to square on the top of pivot-spindle b of Fig.

4. Fig. 6 shows the cultivating teeth or plows and the relations of spring, spring-rod, sliding pressurethimble, and the operatinglever.-

the upright pivot-spindles b, Fig. 4. The

axles b 1) project outwardly from the lower end of said spindles to receive the wheels :20. To theinner side of the spindles, opposite the axles, I attach direct foot-levers B,-projecting inwardly, having free ends, and provided at for the operators feet. By this construction the freeend foot lovers, the axles, and the frame will be supportedin proper position by the upright spindles,while the foot-levers, the axles, and the wheels are adapted to be easily worked by the driver in the angular manner necessary to guide the machine, and the force of the drivers foot is communicated to the wheels in the most direct manner and with the leastpossible friction. By having thelong vertical pivots in the form of a tube the important bearing-surfaces are entirely protected their extremities with foot-rests or stirrups and have the best possible construction for retaining oil.

The tubular pivot-bearings are a very essen tial feature in the field, where the wheels rolling in the soft earth are continuallylifting and scattering dust over the machine. Thus the free, easy, alert action of the swivel-gear can always be depended on, and the operator is enabled to guide this machine promptly and exactly to the corn-row, and can instantly avoid damage to the plants, should there be an irregular movement of the team. In this new form of steering-gear the friction developed and the effort required to operate are not at all increased when the machine is set into deep heavy work, whereas-in such a case the labor on other cultivator-s is greatly-multiplied.

To suit the feet of the operator, as Well as to suit different varieties of work, I provide that the entire swivel-gear shall have a sliding adjnstment upon the frame N by means of any suitable form of holes and clamping-bolts, as at a, Fig. 1, and at a, Fig. 2. This adjustment of the part A upon the frame controls the position of stirrups, foot-levers, axles, wheels, uprightspindles, and rock-arms c. Said rockarms are fitted to squares on the top of the part b, or otherwise fixed to the same, and project in a line parallel with the wheels. The free ends of the rock-arms are then yoked together by the cross-bar D, the connection being made by removable joint pins or bolts at C, Fig. 1, said bolts entering suitable holes in the bar D. It is essential that the wheels be kept parallel. This is accomplished by vary ing the connections of the bar D. The adj ustment of the part A upon the frame before described necessitates a corresponding adjustment between the rock-arms c. For this purpose suitable holes are provided on the said bar at d, Fig. 1. Said adjusting-holes maybe variously located, but should correspond with the adjustment of the swivel-gear before mentioned.

The casting A has a forearm or brace, Fig. 2. This brace at its fore end pivots on the fixed bolt a, Fig. 3, when the rear part slides on the frame where the adjusting-bolts are located. This construction removes most of the draft-strain from the clamp-bolts and greatly steadies the swivel-gear when the clamp-bolts are slackened to change the position of the parts. Much of the usual cramping and twisting of the sliding parts is prevented, and the adjustment is easily effected by a single person without assistance.

The attachment of the cultivatingteeth to the carriage is shown in Fig. 6, in which 0 is the drop part of the frame, stiffened by the brace I. M is the joint-bolt or draw-rod, to which the beams are hinged in such a manner as to permit free movement of the plows up and, down by means of the operating-lcver. Sidewisc the gangs of teeth have adjustment with reference to the corn-row. This adjustmentis limited and controlled by the side brace or braces, J, Fig. 7 One end of the brace is attached to the gangs between the draw-rod and the plows. The other end is attached with a joint or hinge to the rigid frame, preferably at 0, Fig. 7. Thus the free up-a-nd-down movement of the plows is still permitted and the side motion of the plows is entirely prevented. In order to make the central row-space wide or narrow, as may be desired, I provide that the brace shall have adjustable attachment to hold the gangs I I I sidewise in different positions with reference to the frame.

If desired, the brace may be reduced to the single form, instead of being made double or two-pronged.

A suitable adjustment of the brace is shown at Fig. 7 in the form of a clamping-bolt, for the purpose of setting the gang at various distances from the corn-row. The function of this side brace is very important in this particular class of cultivators, as the teeth are required to obey the wheels at once when the machine is guided either to the right or left by the steering-gear heretofore described. Otherwise the teeth could not be guided closely to the corn.

It will be understood that the side brace, J, is not intended to affect the relation of the teeth or plows one to another in the same gang. This latter function is performed by the spreader-braces K K, Fig. 7.

To compel the action of the teeth in hard soil, and to raise the same out of engagement with the ground, I employ the spring-wound pressure-rod F, which is attached to the gang below, and has its upper end placed within a sliding thimble orcye, G, attached to the lever H, Fig. 6, the construction being such that the downward pressure of the lever compresses the spring, the thimble Gsliding freely on the red, as variations of the upward or downward pressure may require. The uplift of the teeth is effected by the thimbleG rising to the hook at F, which enables the lever to be latched up on the quad rant, thus holding the teeth suspended above the ground for traveling on the road.
